為強化防災之需求,本研究針對臺灣西部各河川流域中高於1000公尺之高山地區,說明各流域自動氣象及雨量測站之分布情形,並利用2009-2011年全臺整合雷達資料之強回波出現頻率分布來統計出常發生強降雨之位置,為中央氣象局未來考慮新增之測站位置。此外,為配合中央氣象局增站規劃,本計畫也將進一步探討雲林及嘉義境內各河川流域中可增設站點之位置,以作為中央氣象局近期增站之參考。
n order to reinforce the requirement from flood mitigation, the automatic weather stations and rain gauges distribution along the river basin is studied. In this project, the station elevations above 1000m are primarily focused. In addition, the intense radar reflectivity frequency during 2009-2011 will be studied. The result of the frequency distribution is equivalent to the heavy rainfall area and it will be used to provide suggestions installing new weather stations. Additionally, the radar frequency study will also be focused on the Yun-Lin and Chia-Yi counties to support the near future station revising plan in these two counties.
